AR22 barrel question

[CTown137]

I just picked up a Tactical Solutions M4 22 upper. My plan is to set it up to match my everyday rifle. I currently run an 11.5" SBR. I am wanting to cut down my 22 barrel to 7.5" (leaving 6.5" in front of the upper receiver). Then I am going to thread on my suppressor to make it about 11" total to match up with my SBR.

My question is should I find someone that can cut down my current barrel (which I believe is steel lined aluminum) or is there someone that sales custom barrels for my TacSol upper and I can just get a new barrel.

I am not looking at going super short, like the 4.5", as keeping the rounds sub sonic is not a high priority. And I have a 9.5" handguard that I am planning on running so that it matches my SBR.

I contacted TacSol and they won't cut my barrel down or make me a new one in the length I want.

Any input or contact info would be great!

i would be willing to bet Clint Beyer will make you any length barrel you want, and it will be of better quality than the tacsol barrel.

Although this may not be your primary concern now, I would highly reccomend going with the 4.5" barrel so that most 22LR bulk pack ammo stays subsonic. I made the mistake with my 22LR SBR of going with a 6.5" barrel. Once that Form 1 is approved, you can't shorten the existing barrel. Once you start running stuff suppressed with subs, the sonic crack of rounds going super sonic becomes highly annoying.

I checked out the Better Barrels. They offer a 4.75", bunsen27 would that keep the rounds subsonic?

I am not to up to speed on the AR22's yet, but I saw that my Tac Sol has some sort of collar around the chamber of the factory barrel. Does anyone know if that collar would fit onto a Better Barrel?

I will be pondering my rifle set up and looking on whether or not the shorter barrel will work for what I want.

Thanks for your guys help!

4.75" might work for most bulk pack. I run my Sparrow on a Walther P22 Target which has a 5" barrel and about 30% of Federal bulk pack (1260fps) will go super sonic. I'll be shooting along: pff-pff-pff-CRACK-pff-CRACK. Now my Ruger 22/45 with a 4" barrel 100% of bulk pack stays subsonic. Remember though that I'm barely 300ft above sea level and you're likely in excess of 4000ft above sea level. Different density alltitudes, so slightly different fps (~15fps) for transonic barrier. I think yours would be lower as your DA is higher (thinner air less resistance) so I'd error on the shorter barrel length.
